We compared workplace AI tools on drafting, meetings, search and everyday task help. Our pick for most workers is one general assistant such as ChatGPT or Copilot, plus Otter.ai for meetings, since those cover the largest share of office work.

Ideal for: General work assistant

Our first look at ChatGPT starts with who it serves best. It is the default general assistant for office work. ChatGPT drafts emails, summaries and reports, and answers research questions fast.
The catch is verification: key facts still need checking. It fits most knowledge workers as a daily assistant. Check the current pricing page before you commit, since plans in this category change often, and use the free plan or trial to confirm the fit with your own work.
Before you pay for ChatGPT, run one real task through it, such as a full document, a full trip plan or a full project, and judge it on that result rather than on the marketing page.

Ideal for: Google Workspace assistant

For many readers, Google Gemini will be the most practical choice on this list. It is the Google Workspace equivalent of Copilot. Gemini summarises documents, drafts in Docs and answers questions from your files.
The catch is paid tiers for the best features. It fits Google Workspace teams and users. Check the current pricing page before you commit, since plans in this category change often, and use the free plan or trial to confirm the fit with your own work.
A useful test for Google Gemini is to try the exact workflow you will repeat weekly, then check how long it takes and whether the output needs heavy fixing before it is usable.

Ideal for: Microsoft 365 assistant

Next up is Microsoft Copilot, which takes a different approach to the same job. It is the Microsoft 365 assistant for Office-heavy work. Copilot drafts, summarises and answers questions inside Office apps.
The catch is cost stacking on top of Microsoft subscriptions. It fits Microsoft 365 organisations. Check the current pricing page before you commit, since plans in this category change often, and use the free plan or trial to confirm the fit with your own work.
When you trial Microsoft Copilot, note what is missing as well as what works, since the missing piece often decides whether a tool survives past the first month.

Ideal for: Long documents and editing
Claude earns its place here for a specific kind of user. It is the long-document specialist. Claude edits and summarises long reports while preserving tone and structure.
The catch is breadth: it is a writing tool, not a full office suite. It fits workers handling long reports, proposals and policies. Check the current pricing page before you commit, since plans in this category change often, and use the free plan or trial to confirm the fit with your own work.
We would also check support and documentation for Claude during the trial, since a tool you cannot get help with becomes expensive in staff time even when the subscription looks cheap.

Ideal for: AI inside your workspace
If the options so far have not fit, Notion AI is worth a closer look. It is the workspace AI for Notion teams. Notion AI summarises, drafts and answers questions across your workspace.
The catch is lock-in: it only helps inside Notion. It fits teams already running docs and tasks in Notion. Check the current pricing page before you commit, since plans in this category change often, and use the free plan or trial to confirm the fit with your own work.
Before you pay for Notion AI, run one real task through it, such as a full document, a full trip plan or a full project, and judge it on that result rather than on the marketing page.

Ideal for: Cleaner workplace writing
Grammarly is the option we point to when a reader has a clear priority in mind. It is the writing-quality layer for office communication. Grammarly fixes grammar, clarity and tone as you write email and documents.
The catch is scope: it will not plan your day or summarise meetings. It fits anyone who writes a lot at work. Check the current pricing page before you commit, since plans in this category change often, and use the free plan or trial to confirm the fit with your own work.
A useful test for Grammarly is to try the exact workflow you will repeat weekly, then check how long it takes and whether the output needs heavy fixing before it is usable.

Ideal for: Meeting notes and summaries
Another strong contender is Otter.ai, and it stands out for one clear reason. It is the meeting assistant for busy calendars. Otter transcribes and summarises meetings into searchable notes.
The catch is the free cap for heavy meeting users. It fits workers with frequent meetings. Check the current pricing page before you commit, since plans in this category change often, and use the free plan or trial to confirm the fit with your own work.
When you trial Otter.ai, note what is missing as well as what works, since the missing piece often decides whether a tool survives past the first month.

Ideal for: Team meeting intelligence
We round out the list with Fireflies.ai, which fills a gap the others leave open. It is the team meeting tool with wider language coverage. Fireflies records, transcribes and summarises across meeting platforms.
The catch is free-tier limits on AI summaries. It fits teams sharing meeting notes across tools. Check the current pricing page before you commit, since plans in this category change often, and use the free plan or trial to confirm the fit with your own work.
We would also check support and documentation for Fireflies.ai during the trial, since a tool you cannot get help with becomes expensive in staff time even when the subscription looks cheap.

Ideal for: Research with cited sources
Perplexity rounds out our shortlist with a focused set of strengths. It is the research assistant with sources attached. Perplexity answers questions with cited sources, which speeds up verification.
The catch is that citations still need checking against originals. It fits workers researching topics with source trails. Check the current pricing page before you commit, since plans in this category change often, and use the free plan or trial to confirm the fit with your own work.
Before you pay for Perplexity, run one real task through it, such as a full document, a full trip plan or a full project, and judge it on that result rather than on the marketing page.
We compared official feature pages, pricing pages, app store listings, privacy policies and public reviews for each product, and kept only products that exist, work today and truly fit the topic. We favoured clear pricing, a usable free plan or trial, and honest limits over long feature lists. Where a price could not be verified on the vendor site, we wrote See website rather than guessing.
We did not claim hands-on testing we did not do. Instead, we weighed what each vendor documents, what reviewers report in practice, and where each product falls short, so the trade-offs below are stated plainly.
Pick one assistant for drafting and one tool for your biggest repeated task, such as meetings or research. Set a rule for checking AI output before it leaves your desk, and drop any tool that adds review time without removing a task.
ChatGPT and Copilot suit most office work, Claude suits long documents, and Perplexity suits cited research. Otter.ai suits meeting-heavy roles.
A general assistant plus a meeting tool covers most office productivity needs. Notion AI suits teams already using Notion, while Copilot suits Microsoft 365 teams.
Check your employer policy and the tool privacy terms before uploading sensitive documents. Business and enterprise plans usually offer stronger data controls than free tiers.
No, they automate parts of drafting, summarising and research, but judgement, relationships and accountability remain human work. The best use is removing routine tasks, not replacing roles.
Perplexity suits research with cited sources, while ChatGPT and Gemini suit broader research and synthesis. Always verify key facts against primary sources.
